Phpbb 3.0 edit post with curl from bash script

[kot7k]

Hi i really didnt know where to post this, but here it is in case someone can help me.
i just wanted to make a little bash script to automatize some actions i do on my forum on a regular basis. I was perfectly able to reply to a post in my forum following this example:

Code: Select all

#!/bin/bash

LOGINURL="http://.../ucp.php?mode=login"
POSTURL="http://.../posting.php?mode=reply&f=xx&t=xx"

USERNAME="..."
PASSWORD="..."

#retrieve cookies
curl -s -d "username=$USERNAME" \
        -d "password=$PASSWORD" \
        -d "login=Login" $LOGINURL -c cookies.txt

#get necessary posting information
curl -s $POSTURL -b cookies.txt -o "post.html"

#yes - this could be improved
postid=$(grep 'topic_cur_post_id' post.html | cut -d'"' -f6)
lastclick=$(grep 'lastclick' post.html | cut -d'"' -f12)
creationtime=$(grep 'creation_time' post.html | cut -d'"' -f6)
formtoken=$(grep 'form_token' post.html | cut -d'"' -f6)

POST="whatever you want to post...."

#wait some seconds -- won't work without
echo "waiting 10 seconds..." && sleep 10

#post your message
curl --data-urlencode "message=$POST" \
     -d "topic_cur_post_id=$postid" \
     -d "lastclick=$lastclick" \
     -d "creation_time=$creationtime" \
     -d "form_token=$formtoken" \
     -d "post=Submit" $POSTURL -b cookies.txt

#cleanup
rm cookies.txt
rm post.html

However i wanted to edit my post, I found this in this webpage: http://fabianmaass.de/?p=133 The guy also says that if you want to edit a post instead of reply to it you have to change some lines to this:

Code: Select all

lastclick=$(grep 'lastclick' post.html | cut -d'"' -f6)
creationtime=$(grep 'creation_time' post.html | cut -d'"' -f6)
formtoken=$(grep 'form_token' post.html | cut -d'"' -f6)

curl --data-urlencode "message=$POST" \
     --data-urlencode "edit_reason=$EDIT_REASON" \
     -d "lastclick=$lastclick"  \
     -d "creation_time=$creationtime" \
     -d "form_token=$formtoken" \
     -d "post=Submit" $EDITURL -b cookies.txt

I did it but what curl returns to me is the post contanting my edited message also with the submit button on it. So it seems to fill the text but doesnt seem to click on submit button. No changes are made on my forum post. Anyone knows what i am missing? Cause reply code works, and i am also sending post=Submit in edit code too.

That is no post - that's the editor. And you also haven't said if it contains a preview or error messages.

I wonder how it works for you fine in the first place, since in both examples you don't provide any post subject. Your scripts also make nowhere sure the variables filled thru grep actually have content - how about printing this to your shell so you halfway know where things break?

Submitting an edited post on this board looks like this:
